Further Notes on North Dakota Birds

Notes from Luce County, Mich.--ARcTic THREE-TOED WOODPECKER (Picoides arcticus).--Theobservation of an individual of this species on June 24, 1924, about two miles south of McMillan, Michigan, would indicate that it had a nest in the vicinity.Since that date I have seen a single bird of this species on September 11, 15 and 20 and October 19.With the exception of the last observation the bird was always seen in the top of a dead evergreen on the east side of McCormick Lake.HARR•S'S StARROW (Zonotrichia querula).---OnMay 21, 1924, I heard an unfamiliar bird song and upon investigation found it to be the song of the Harris's Spa•Tow.The birds were rather common for about a week, in the yard where the chickens were fed, and also about a box in which I put food for the birds.TREE SWALLOW (Iridoprocne bicolor).--TreeSwallows have nested in my bird houses since the summer of 1919 and I have been interested in noticing the difference in the time of their arrival since they have established a home here.From 1917 to 1919 my first arrival date was May 17, 31 and 15 respectively, while from 1920 to 1924, after they had taken possession of my boxes, the dates ran April 18, 19, 18, 20 and 19.--Dates of departure that I-have recorded are July 31, 1922, and August 28, 1924.--O.M. BRYANS, McMillan, Michigan.Further Notes on North Dakota Birds.--CoorER'sHAWK (Accipiter cooperi).--Thisspecies was noted but once by the writer in his North Dakota work.We now have three in the museum collection, taken by H.
